Answer:
3.99 inches
Step-by-step explanation:
<u><em>The correct question is</em></u>
The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.
What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth
we have
This is a exponential growth function
where
f(x) represent the length (in inches) of an image
x is the number of times the image is enlarged
so
For x=3
substitute in the exponential equation
Answer:
The indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
Step-by-step explanation:
Let the drying times of type A be the first population and the drying times of type B be the second population. Then
We have small sample sizes 
and 
, besides 
, 
, 
and 
. Therefore, the pooled
estimate is given by
The 99% confidence interval for the true mean difference between the mean drying time of type A and the mean drying time of type B is given by
, i.e.,
where 
is the 0.5th quantile of the t distribution with (11+9-2) = 18 degrees of freedom. So
, i.e.,
the indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
Answer:
28/15
Step-by-step explanation:
Convert the mixed numbers to improper fractions, then find the LCD and combine.
5 ft 3 in - 5in = 4 ft 15 in - 5 in = 4ft 10 in
Answer: 4ft 10 in
Answer: 12 miles
Step-by-step explanation:
Hi, to answer this question we have to write a growth equation.
Total miles = 8 (1 +0.05)^9 = 12.41 =12 miles
Where 8 is the initial miles she run, since is increasing each week by 5% we have to multiply it by 1+ percent increase rate in decimal form (1+0.05) to 9th power (number of weeks)
She will run 12 miles in 9 weeks.
